Maize (Zea mays L.) is one of important cereals of tropic and tropic countries. It serves as the raw material for starch production. Among starch types, ‘resistant start’ is considered more beneficial for human health. Hence, the genotype (of maize) gains significance in selection for commercial cultivation. However, nutritional information on starch digestibility of maize genotypes is scarce. In this context, we analyzed a set of 80 maize hybrids for carbohydrate profile (sugar, starch, amylose, amylopectin) and resistant starch content. The results revealed significant variation for carbohydrate profile and resistant starch content among diverse maize hybrids. Pratap QPM Hybrid was found to be the highest, followed by FCH 184, RMH 3591, NT 6240 and CO 1 in terms of sugar content. For total starch, Rasi 3033 hybrid proved the best genotype followed by L 333 and HQPM 7. The genotype LG 3271 exhibited highest amylose content followed by Bio 9544, P 3502 and DHM 119, whereas NMH 731 was found to possess highest amylopectin content followed by Janahit 5053 and KDMH 176. For resistant starch, LG 3271 was the best genotype followed by P3502, KH 2192 and HQPM 1. Amylose and resistant starch content showed highly significant positive correlation (r = 0.550^**), whereas highly significant negative correlation has been observed between amylopectin and resistant starch content (r = -0.548^**). The scanning electron micrographs of genotypes having the highest and the lowest values of resistant starch revealed substantial differences in the granular structure showing that starch granules are compactly packed in the LG 3271.

了解印度玉米杂交种的淀粉消化率特性

玉米（玉米）L.）是热带和热带国家的重要谷物之一。它用作淀粉生产的原料。在淀粉类型中，“抗性启动”被认为对人体健康更有益。因此，（玉米）基因型在商业种植选择中具有重要意义。但是，缺乏关于玉米基因型淀粉消化率的营养信息。在这种情况下，我们分析了80个玉米杂交品种的碳水化合物概况（糖，淀粉，直链淀粉，支链淀粉）和抗性淀粉含量。结果表明，不同玉米杂交种的碳水化合物特征和抗性淀粉含量差异很大。发现Pratap QPM Hybrid的糖含量最高，其次是FCH 184，RMH 3591，NT 6240和CO 1。对于总淀粉，^**），而支链淀粉与抗性淀粉含量之间存在高度显着的负相关性（r = -0.548 ^**）。具有最高和最低抗性淀粉值的基因型的扫描电子显微照片显示，颗粒结构存在显着差异，表明淀粉颗粒被紧密包装在LG 3271中。
